温度对消失模铸造涂料透气性的影响
Effect of TiB 2 Fabricated by Direct Reaction Method on Silicon Morphology of ZL101 alloy and Efficiency of Modifier for ZL101 Alloy
【摘要】 本文研究了消失模涂料透气性随温度变化的规律 ,并从空气粘度、耐火骨料热膨胀和有机物热分解三个方面分析了温度对涂料透气性的影响
【Abstract】 ZL101/TiB 2 composite was fabricated by direct reaction method.The modification effect of K,Na and Sr modifiers is obviously decreased by TiB 2 and B.The morphology of eutectic silicon in composite is coarse plate.The strength of ZL101/TiB 2 is slightly lower than that of ZL101 matrix.
